Finite-volume effects on smeared spectral densities
Francesca A. Bresciani, Mattia Bruno, Maxwell T. Hansen
Using two distinct approaches, we derive a universal expression for the leading finite-volume effects of the smeared vector-vector spectral density (proportional to the smeared had…
Bounding statistical errors in lattice field theory simulations
Mattia Bruno, Gabriele Morandi
Simulations of strongly interacting lattice field theories are typically performed using Markov chain Monte Carlo algorithms. Therefore estimators of statistical errors must incorp…
Thermal evolution of dark matter and gravitational-wave production in the early universe from a symplectic glueball model
Mattia Bruno, Niccolò Forzano, Marco Panero +1
The hypothesis that dark matter could be a bound state of a strongly coupled non-Abelian gauge theory is theoretically appealing and has a variety of interesting phenomenological i…
Spectral densities from Euclidean-time lattice correlation functions
Matteo Saccardi, Mattia Bruno, Leonardo Giusti
In quantum field theories, spectral densities are directly related to relevant physical observables. In Lattice QCD, their non-perturbative extraction from first principles require…
